Passkey on phone works to sign in to AWS Console but not Amazon Q

Based on the information provided, it appears you're experiencing an issue with your passkey authentication when trying to sign in to Amazon Q in VS Code on your laptop.

AWS passkeys are designed to work with specific AWS services, and they are registered per service and device. The passkey you've generated in AWS IAM works for the AWS Console because that's where you registered it. However, Amazon Q might be using a different authentication system or requiring a separate passkey registration.

To resolve this issue, you have a few options:

1. Register a new passkey specifically for Amazon Q. You would typically do this during the first-time setup process for Amazon Q.

2. If you're using a synced passkey (through providers like iCloud Keychain, Google Password Manager, 1Password, or Dashlane), ensure that your passkey is properly syncing across your devices.

3. If you're using a security key (like a YubiKey), make sure it's properly connected to your laptop when attempting to authenticate.

4. Check if Amazon Q supports the same authentication methods as the AWS Console. It's possible that Amazon Q might have different MFA requirements or might not yet support the same passkey implementation.

If you continue to experience issues, you might need to contact AWS Support specifically about Amazon Q authentication, as this appears to be a service-specific authentication challenge rather than a general AWS IAM passkey issue.
